Leela-zero: Leela zero will kill itself while training
I used Leela Watcher to see Leela zero training, but I find Leela zero sometimes will kill itself. Leela possibly put stone to the second eye and make two eyes to one eye. I wonder it is a bug? or just works as design? See sgf file below:
sgf Link (go into link and select "2018-02-23T09_30_27.176Z.sgf" to download)
Test Environment:
leela-zero-0.12-win64 with LeelaWatcher-1.1.0.jar
OS: Windows 10 x64
GPU: NVIDIA Geforce GTX 960M

Look at these games in edit mode, and you will notice that the player filling in their own eyes is always losing even before that. The suicide is a hail mary play that aims to extend the game when passing would lead to a loss. As far as I've seen, it happens most often in -r 0 games, where resignation is disabled.
So, not a bug. With current networks, LZ very rarely kills its own group when it would have been winning otherwise. It just doesn't know how to lose in style, as we would define it in a human way.
